产前超声诊断胎儿侧脑室增宽及合并畸形

目的 探讨产前超声诊断胎儿侧脑室增宽合并胎儿结构畸形的临床价值。方法 回顾性分析2006年1月—2010年6月来我院检查的27 027名孕妇中超声检出的293胎侧脑室增宽胎儿的超声检查资料。结果 293胎侧脑室增宽胎儿中,未合并胎儿结构畸形232胎(232/293,79.18%);合并胎儿结构畸形61胎(61/293,20.82%),其中最常见的合并畸形为神经系统畸形(42/61,68.85%),其次为心血管系统畸形(21/61,34.43%)。结论 产前超声检查发现胎儿侧脑室增宽时,应仔细检查胎儿各系统结构,了解有无合并胎儿结构畸形,尤其是神经系统和心血管系统。对于仅有侧脑室轻度增宽而无明显结构畸形的胎儿,在妊娠后期也应加强随访。

Prenatal ultrasound diagnosis of lateral ventriculomegaly and abnormalities

Objective To investigate the value of ultrasound in diagnosing fetal lateral ventriculomegaly (VM) and structural malformations. Methods From Jan 2006 to Jun 2010, 27 027 pregnant women underwent ultrasound, and 293 fetuses with lateral VM were detected. Results Among 293 lateral VM fetuses, lateral VM occurred as an isolated abnormality in 232 fetuses (232/293, 79.18%), combining with other associated structural malformations in 61 fetuses (61/293, 20.82%), common abnormalities mainly included nerve system anomalies in 42 (42/61, 68.85%) and cardiovascular system anomalies in 21 (21/61, 34.43%) fetus. Conclusion Once lateral VM was detected with ultrasound, it is suggested to check fetal structure carefully, especially nerve system and cardiovascular malformation. Moreover, it is necessary to strength prenatal follow-up survey for mild lateral VM fetus without structural malformations.
